Core Manufacturing Technologies & Process Advantages

1. Precision ABS Injection Molding Technology
- Process Parameter Control: Molding temperature ranges from 180-240℃, mold temperature from 40-80℃. Melt Flow Rate (MFR: 1.8-10g/10min) is adjusted according to ABS grades (e.g., ABS 757, ABS 8391) to ensure complete filling of complex structures.
- Key Technologies: High-speed injection molding (injection speed 50-150mm/s) reduces weld lines; graded holding pressure control (30-60MPa) minimizes shrinkage; dimensional tolerance reaches ±0.05-0.1mm.
- Application Scenarios: Mass production of complex structural parts such as automotive interior components, electronic enclosures, and medical device housings.
2. Precision ABS CNC Machining
- Equipment & Accuracy: 5-axis CNC machining centers with positioning accuracy of ±0.005mm, supporting milling, drilling, and turning of ABS sheets and rods.
- Technical Points: PCD tools are used to reduce material chipping; cutting speed is controlled at 150-250m/min; cutting parameters are optimized for flame-retardant ABS (e.g., ABS FR-1) to avoid flame retardant decomposition.
- Application Scenarios: Low-volume prototypes, high-precision mechanical structural parts, and customized assembly accessories.
3. ABS-Specific Post-Processing Technologies
- Surface Treatment Technologies:
-
- Texture processing (Mold-Tech standard textures) to enhance hand feel and appearance.
-
- Ultrasonic welding (welding frequency 20-40kHz, pressure 0.2-0.5MPa) for seamless splicing of ABS parts.
-
- Electroplating/painting pre-treatment (degreasing, roughening processes) to ensure coating adhesion ≥4B grade (cross-cut test).
- Assembly Integration: Thermal insertion of threaded inserts (temperature 200-240℃, pressure 10-30N) with pull-out force ≥500N, meeting long-term service strength requirements.

- DFM Design Optimization: Engineering team provides free DFM (Design for Manufacturability) analysis, optimizing part wall thickness, fillet radius, draft angle and other structural designs to avoid processing risks and reduce production costs.
- Material Selection & Prototyping: Select ABS grade based on requirements, produce 1-5 samples (3-5 working days), provide dimensional inspection reports and performance test data; proceed to the next step after sample approval.
- Mold Development/Process Programming: Mold opening for injection-molded parts (7-15 days), programming for CNC parts; synchronize mold/program progress throughout the process, allowing customers to check at any time.
- Mass Production & Quality Inspection: Mass produce according to approved sample standards; randomly inspect 3-5% of each batch for full-dimensional testing and performance sampling; immediately reject defective products.
- Packaging, Delivery & After-Sales Service: Independent packaging with anti-static bags/bubble wrap, ship via agreed logistics method; provide 1-year quality guarantee and 7×24-hour after-sales technical support.
Common Processing Issues & Professional Solutions
|
Common Issues
|
Causes
|
Solutions
|
|
Surface Sink Marks/Depressions
|
Insufficient holding pressure, uneven wall thickness, low mold temperature
|
Optimize holding pressure curve (graded holding pressure 30-60MPa), unify wall thickness to 2-4mm, increase mold temperature to 60-80℃
|
|
Obvious Weld Lines & Insufficient Strength
|
Low melt temperature, slow injection speed, unreasonable gate location
|
Increase melt temperature to 220-240℃, adopt high-speed injection (≥80mm/s), optimize gate quantity and location
|
|
CNC Machining Chipping & Burrs
|
Insufficient tool sharpness, improper cutting speed
|
Use PCD special tools, adjust cutting speed to 180-220m/min, add climb milling process
|
|
Coating Peeling & Poor Adhesion
|
Unclean surface oil, inadequate pre-treatment
|
Adopt “degreasing → roughening → electrostatic dust removal” three-step pre-treatment; cure at constant temperature after painting (60℃/2h)
|
|
Dimensional Deviation Beyond Tolerance
|
Mold wear, fluctuating molding parameters, uneven material shrinkage
|
Regularly calibrate molds and processing equipment, adopt closed-loop control of molding parameters, select high-flow ABS grades to reduce shrinkage fluctuation
